BEFORE          AFTER The thread insert is fitted by screwing it on to the AMECA instrument threaded pin, with a knob or handle, until the drive hooks on to its end. Screw the assembly into the threaded hole until the insert is completely in, then turn by 1/4 or 1/2 turn. Either with the handle

Or with the knob
(up to diameter M8)

The advantages - CAN BE USED:
for a first installation, for repair, for reworking


• Cannot come loose
The outer diameter of the AMECOIL® SR thread insert has a larger diameter than that of the threaded hole. Adhering strongly to the threaded hole, it can practically never come loose once installed.
• Resistance to corrosion and other threats
The AMECOIL® SR thread insert prevents deterioration of threads due to pulling, vibration, fatigue, seizing or corrosion while resisting the highest temperatures.
• Regular distribution of loads
• Reduction of bosses
• Resistance to premature wear
• Simplification of locking systems
From +0.1 to +1 mm of the nominal diameter of the screw.
Performed with the AMECOIL® tap.
Using the tools of the conventional series or those of the new series, for even quicker installation.
Using the threaded pin of the AMECA tool, fitted with a handle or knob.
